"of theexerciser, but illustratingsome variations in thearrangementrof'FigV-i. .n `Referring to the drawing, andparticularlyitoFigsqy 1? and 2, thereis shownjra handle 'l :extendingdiametrically j across a lring 2,-the handlev being-.appropriatelyshaped to be grasped bythe hand o'i the user, which hand is thenencircledby the ring 2.; The handle `1- maybe made either I actuallyoreectively in onegpiece with the ring 2,"v although:l this isf'notobligatory. Formed in the outer periphery.otthering 2 is a groove 3.extending :wholly aboutthe ring and constituting-one memberoil arace forantifriction balls 4:.7k vSu rroundinglthe ring 3fis another ring 5khaving. a ball-,race 6 about' its ,inner circumference, .the -two ringsbeing held together by a circular series of the balls'l which not onlyvforman antifric-tion bearing forv the movement `of g the ring 5 aboutthe ring 2, b utalsok lockl the two Projectingl from the fouterperiphery of the ring 5 is an armk?, the direction o'j pirojection`being preferabljg though not f necessarily, radial. The. aun-1'2"y isshown -jas hollow 'or tubular and internallyg. screw7 threadedV toreceive one .end of a threaded stem S', theotherend oi which .carries aninertia member 9 shown as in the form of aball, but it is to beunderstood,thatsuch Y' kparticular' form is not obligatory.` FurtheI'-,

more, the bally 9 isjindieatedfasprovided with a covering lwhich may, bypreference, be kof softy rubbenor any other suit,- able materialdesigned toprevent injuryin case Vthe inertia member strikes anylthing.rA lock nut .lilapplied 'to kthe stem Sserves to lock thestem in anyladjusted ,position so that the ball 9'1nay be .-loc;ate d `at differentdistances from thejhandlel. The bore of the arm 7 is continued throughthe ring 5 so lr1.0 f

as to open into the ball race-way in the ring 5, whereby the ring may beIilled with balls through the arm 7 and then the balls are preventedfrom escaping or jamminggby a screw plug 12 introduced into the arm 7 toa point suliciently close to the balls to prevent jamming thereof.

With an exercising device such as shownV in Figs. 1 and 2, the hand ofthe user grasps the handle 1 with the ring 2 arranged trans.

versely of the length of the arm, or by bend- Y ing the wrist the ring 2may be madeto as sume another angular relation to the length ofthe arm.Now by imparting a swinging movement, especially about an axiscoinciding with the shoulder joint, the inertia member 9 is causedtoorbitally move about the handle land the hand grasping the handle. Theinertia ofthe ball 9 tends to impart to it tangential movements and ifthe orbi: tal movements b e rapid the tangential tendency will becomepronounced, so that a considerable muscular eflort'must be exerted tomaintainv theorbital movements of the inf' erti-a member. and to kkeepthe bodily 1nove ments of the whole device within a reasonably sinallcircular path. If the ring 2 be so held that the orbital movements oftheball 9'approachparallelism with the length ofV the users arm, certainmuscles will come intolplay which were not aii'ected by the` movementsofthe inertia ball in planes substantially perpendicular to thelength ofthe arm. The device is susceptible of use in various ways and maybeeasily manipulated in different manners t-o affect many muscles of thearms, chest, back and lower portions of the body, and even of the neck.

The exercising device may be made withV the stem carrying the inertiamember more or` less elastic to give a certain amount of elasticity'with Va corresponding Veiitect and change of exertion on the part oftheperson Y exercising. Moreover, the structure may be of anchoring thewires in the ball may ybe employed. At the other end the stem is'anchored in aringa corresponding the ring 5 of the structure of Flg.' 1.This anchoring is performed by passing the inner end of the stem partlythrough a boss 7*"v corresponding to the arm 7 of Fig. v1, but

much shorter and opening into a race-way 6 corresponding to therace-ways of the structure of Fig. 1.V A plugl, of lead or the like,maybe used to hold the inner end of the stem 13, the wires of which werehold in the ring 5a being spread to prevent' retraction or loosening. L

l VTo permit the introdnctionof balls into ,the race-way an opening 16is formed at any convenient point in the ring 5a and is 'closed by aplug 17 `introduced after the balls `have The structures of Figs. 1,'and 3 are susceptible of considerable` elaboration, representingVcorresponding, cost of production.

or such surface may be omitted To provide a cheaperpthoughnin. many re-Y spects equally as effective, structure, the cost of production maybematerially reduced along thelines 'shown in Figs. -iand 5. In Fig. 4there is shown Aafhandle 1.8 similar in shape to the handle'll of Figs.1 and 2 andl somewhat differently constructed, and

this handle is madeV separately for cheapness. of construction.Surrounding the handie l is a ring 19 which may comprisea trough shapedor channel strip ofV metal Ibent into ring form and providedfwith ra-Adially outward flanges 20. 1 The 4strip 19 Where the ends meet overlaps,as indicated at 21, and one of two screws 22 holding the handle 18 andring 19 together may be made to traverse vthe overlapping portion and sosecure the overlapping meeting ends of. the ring together. Seated inthechannel thus formed bythe flanges 20 is a metal strip 23 encircling thechannel strip 19'and having prolonged meeting ends 24C secured togetherat intervals by rivets 25 or in yother appropriate mannen'theprolongations 24:, when riveted together, constituting a stem26corresponding to the stems 8 and 1-3 of Figs. 1, 2 and 3. The outerextremities of the prolongations '24 are appropriately bent inVoppositedirections, as shown at 27, to combine into an -emlbracing clippartially encircling -a ball 9b and a rivet28 traversing the ball 9*diametrically and extending through the extremities 27 constitutes "aconvenient means j for securing theparts together. The handle 18 is.formed atlthe ends. with wings 29 of suliicient lengthA to receivebetween them the ring 19 and the flanges 20 so that the screws 22are'not subjectedV to any twisting-strain during the operation of thedevice. InFig. 5 the handle portion andf the'ring carried by the handleareshown as stainped out of sheet'metal. For this purpose two identicalstampingsxare provided, each comprising one-half of a handle member 9cand onehalf ofaringw19` with side .flanges 20, the? two halves `beingconnected by', rivets 30 passed through the handlesections. A TheYstructures ofi Figs. 4 and `5 are designed `for cheap production topermit sale at a'relatively low priceand much lower thanV would 'V bethe casewith the` Astructures of Figs. 1, 2 and `3 and `.especially withrespect to the structureof Figs. 1 and 2 where provision is made for theadjustment of the effective length of the stem 8 to vary the distance ofthe ball or inertia member 9 from the handle l. However, the usefulnessof the structures f ci Figs. 4 and 5 is very similar to that of Figs.v

l, 2 and 3 when considered as exercisers, the

principal ditference, aside from the question of cost, being in thegreater 'ease of move` ment with the structures of Figs. 1, 2 and`3 overthe structures/of Figs. 4 and 5.
